What different in Acb, vcb breaker

Question

Accepted Answer

ACB and VCB breakers are both types of circuit breakers used in electrical systems, but they differ in their operating mechanisms.

ACB stands for Air Circuit Breaker, while VCB stands for Vacuum Circuit Breaker.
ACB breakers use air as the medium for arc extinction, while VCB breakers use vacuum.
ACB breakers are typically used for low voltage applications, while VCB breakers are used for medium to high voltage applications.
ACB breakers are more commonly found in industrial and commercial settings, while VCB breakers are often used in power generation and transmission systems.
ACB breakers are generally larger in size and require more maintenance compared to VCB breakers.
VCB breakers have faster arc extinction times and higher breaking capacities compared to ACB breakers.
ACB breakers are more cost-effective for lower voltage applications, while VCB breakers are more expensive but offer better performance for higher voltage applications.

Accepted Answer

ACB Air circuit breaker is suitable for low voltage range up to 450volts.VCB is suitable for medium voltage range from 11kv to 33 kv

Accepted Answer

The difference between air circuit breakers and vacuum circuit breakers are many. Vacuum circuit breakers are best for hv circuit breaker. Air circuit breakers can be best for medium voltage use. Air circuit breakers are dependable on the arc extinguishing device to stretch the arc.
